The ADM2xx family of line drivers/receivers is intended for all EIA-232-E and V.28 communications interfaces, especially in applications where 12 V is not available. The ADM223, ADM230L, ADM235L, ADM236L and ADM241L feature a low power shutdown mode that reduces power dissipation to less than 5 W, making them ideally suited for battery powered equipment. Two receivers remain enabled during shutdown on the ADM223. The ADM233L and ADM235L do not require any external components and are particularly useful in applications where printed circuit board space is critical.
